If this is one of the previous reviewers favourite places, they need to get out more seriously. As Japaneese goes, its as bad a whaling... full of fat desroys the environment and just a dogs breakfast!
Try walking down the road to the Sushi Train in Newtown and you will taste better Japaneese at a better price. Asakusa is a blight on Newtown and should be made illegal like whaling. Over priced driead up samon, Oily fried dishes and slow service to boot.
If my date took me here, I would dumb them on the basis of their poor selection.
